This bit me on a previous site and it is why the only things in my robots.txt now are routes that redirect to a login and can never carry a tag at all.

Yes, and I would not have called mine faceted nav in a hundred years. It is four sort buttons.

That is a fair correction and it changes what I expect to happen next. I was half expecting the articles to get crawled more. What you are describing predicts no such thing, just less low-value stuff in the index.
